Electromagnetic Induction April 3 rd , 2007 Pre-Questions: 1. Yes because changing the magnetic flux will induce a current. 2. They cannot because they are both dependant on each other. Current will not flow without an emf or else Faraday’s Law would not be obeyed. 3. An induced current produces an induced magnetic field that opposes the change of magnetic flux causing current. Purpose: To observe electromagnetic induction, and the emf produced in a secondary coil when magnetic flux is changed. Method: The procedure was followed (29.3-29.7). Diagram: Data: See attached

Graph: See attached Discussion: This lab did not have that much error since most values were measured on a positive or negative basis. Measuring the values for the graph in part 3 had error since the

Unformatted text preview: galvanometer has internal resistance and the needle did not stay stationary and using a meter stick to measure values. Closing Questions: 1. The ultimate source of energy in part 1 comes from the movement of the bar magnet. Doing this changes the magnetic flux inducing current. 2. The source of energy that appears in the secondary circuit when the primary circuit is broken is the change in distance in the magnet raised above the secondary circuit changing flux and inducing current. When the primary circuit was connected, the energy came from the power supply....

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
